poration of Ohio CleveIan ,,Qhi ac r- Application. October 25, 1945,.Seria-l: No. 624,363.-

This'invention relates generally to metal furniture, but hasreferencemore, particularly to articles. of metal furniture, such as rockers,chairs and the, like, and to a method of manufacturing such; articles.

A primary object of the invention is to provide an article of furnitureofthe character described, which is of rugged, durable construction, andwhich is, neat and attractive, in appearance.

Another objectofthe invention is to provide an article of furniture ofthe character described, which is characterized by the use of sides madefrom metal strip bent or curved into circular form.

A further object of the invention is to provide a metal rocker or chairof novel construction, which can be manufactured and assembled incommercially desirable quantities, at low cost.

A still further object of the invention is to provide a method ofmanufacturing sides for metal furniture of the character described,which method is economical and utilizes metal strip in a novel manner.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawings, forming a part of this specification, andin which like numerals are employed to designate like parts throughoutthe same,

Fig. 1 is a top plan View of a rocker embodying the novel features ofthe invention;

Fig. 2 is a side elevational view of the rocker;

Fig. 3 is a fragmentary cross-sectional View of the rocker, taken on theline 3-3 of Fig. 2;

Fig. 4 is a front elevational view of the rocker;

Fig. 5 is a side elevational view of a coil or helix of metal stripwhich is advantageously employed for making the sides of the rocker;

Fig. 6 is a view similar to Fig. 5, but showing a single convolution cutfrom the coil or helix of Fig. 5 for manufacture into one of the sidesof the rocker;

Fig. 7 is a view showing the manner in which the ends of the singleconvolution of metal strip shown in Fig. 6 are joined or united to formthe rocker side, and

Fig. 8 is a fragmentary side elevational view of a chair embodying thenovel features of the invention.

Referring more particularly to Figs. 1 to '7 inclusive of the drawings,it will be seen that a rocker constructed in accordance with theinvention comprises spaced circular sides I and 2, of semi-circular orarcuate cross-section, the upper 1 Claim. (01. 155 1-194 2 portionsofwhichform or provide-arm restsfor the. occup ofe: rocker.

The rocker further includes a, slightly inclined; seat 3,,preferablyformed ofasheet metalstamp 'ing, and an inclined back or back rest 4',likewise;

formed from a sheet metal stamping, and having: its lower edge rigidlysecured in. any desired manner to the rear edge of, the. seat 3., The,seat. 3. and back, 4 extend completely across the. space between. thesidesl and. 2, and aresupportedjrespectively by orupon anglesorangle;strips 5;.and;

6, which. extend between and. are;- rigidly; secured. to the sides I and2. Theseanglesalso'functionito rigidly maintain the sides I and 2 inproperly spaced relation and in vertical planes, but for this purpose, arod 1 may also be provided, which extends between and interconnects thesides I and 2, at the lower rear portion thereof, and is preferablywelded to the latter.

Under some conditions, where the sides I and 2 are made of sufiicientlylarge diameter, the lower portions of such sides can function as therocker elements which make rolling contact with the floor, butordinarily, I prefer to provide separate rocker elements, which haveextended arcuate central portions 8, of considerably greater radius thanthe radius of the sides I and 2, and rebent or inturned end portions 9and Ill, the ends of which are preferably Welded to the sides I and 2,as best shown in Fig. 2. The extended arcuate portions of the rockerelements provide a desired length of rolling contact of the rocker withthe floor, and avoid tipping of the rocker forwardly or rearwardly atthe extremities of the rocking movement.

The rocker elements are preferably made from strip metal ofsemi-circular or arcuate crosssection, similar tothat from which thesides I and 2 are made, and this permits the sides to nest into thearcuate central portions 8 of the rocker elements, as shown in Fig. 3.The rocker elements may be spot Welded to the sides I and 2 at the pointof nesting, if so desired.

The sides I and 2 can advantageously be made from single convolutions ofa coil or helix of .strip metal of the desired cross-section, such asshown in Fig. 5. Such a coil or helix can be manufactured in longlengths from ordinary flat strip on an ordinary strip formin machine,the forming rolls of which can be set in such a manner that formed stripof the desired cross-section emerges from the machine in the form of ahelix. Single convolutions of the strip can then be cut from the helix,as shown in Fig. 6, and the ends of such convolution may then be weldedto each other,

' as at A (Fig. '7) to form a completed side for the In Fig. 8, I haveshown the lower portion of chair, which, in other respects, is similarin con -v struction, design and appearance to the rocker which has beendescribed. In this case, a strip of metal of semi-circular or larcuatecross-section, similar to that from which the side I is formed, is bentto provide a horizontally disposed central portion H, in which the sideI is nested, downturned arcuate portions l2 formin legs for the chair,and end portions l3, the ends of which are welded to the side I. Rods14, similar to the rod 1; may also be provided, which interconnect thesides of "the chair, the front rod providing a foot restl I r It is tobe understood that the forms of my invention, herewith shown anddescribed, are to be taken as preferred examples of the same, and thatvarious changes in the shape, size and arrangement of parts may beresorted to, without departing from the spirit of'my invention, or thescope of the subjoined claim, r

4 Having thus described my invention, I claim:

'A chair comprising spaced side members each formed from a metal stripof arcuate cross-section having its ends secured together to form anannulus, supporting members each formed ,of a metal strip of arcuatecross-section, said side members being each nested in the channel of asupporting member, the secured ends of each side member lying within achannel of a supporting member to conceal the joint between the ends of7 said side member and means securing said side members together.
